WINDOW STOP Filed Aug. 9, 1928 2 Sheets-Sheet Patented Dec. 31, 1929 orFicE MICHAEL SEAPIRO, 0F BROOKLYN, NEW YORK WINDOW STOP Application filed August 9, 1928. Serial No. 298,414.

My present invention relates to a device adapted to be employed in conjunction with window sashes to limit the movement thereof relatively to one another when, for example, it is desired to open the window a predetermined distance for the purpose of ventilation and at the same time it is necessary to guard against th furth Jr opening of the window to prevent unlawful entry therethrough.

in carrying out the invention the device made in accordance therewith is simply and inexpensively constructed and when applied for use is adapted when in one position to limit the extent of the movement of one window sash relatively to another while when the parts are in another position the window sashes are entirely free to be moved to any position in the customary manner. This device in its preferred form comprises a bracket adapted to e suitably connected to a rail of one window sash, a stop member associated with the bracket, and means making possible a relative movement between the bracket and the stop member whereby in one position the stop member is adapted to prevent more than a predetermined movement of one window sash relatively to the other and when the stop member is set in another position the window sashes are entirely free to be moved to any position relatively to each other, as will be hereinafter more particularly described.

Referring to the drawings 10 indicates a window casing in which in the usual manner a pair of window sashes is mounted. An upright rail of the upper windowsash is indicated at 11 and the lower transverse rail thereof at 12 while the upper transverse rail of the lower window sash is indicated at 13. Thee; parts are illustrated to show the use of the window stop which is the subject 1nattor of the present invention.

The improved window stop preferably comprises a bracket member 14 adapted to be secured against the outer face of the upright rail 11 of the upper window sash by means of screws 15 or otherwise. As illustrated, this bracket member is connected to the outer face of this rail but as will be understood it may be set in a recess therein provided for this purpose in such a manner that the outer face of the body of the bracket lies flush with the outer face of this upright rail. This bracket member 14 is constructed to include spaced socket members 16 and 17'. T he opening in these socket members is illustrated as being square in cross section. It will be understood, however, that in carrying out the invention the opening in these socket members may be made of any mult-i-sided configuration. The device also includes a stop member indicated at 18. This stop member is constructed to include a socket 19 having an opening therethrough which corresponds in cross section with the openings in the sockets of the bracket and, of course, is of the same transverse dimensions as the openings in these sockets. The socket 18 of the stop member is of sufiicient length to fit and lie within and between the sockets 16 and 17 of the bracket. Preferably the body of the stop member depends or extends an appreciable distance from the socket thereof and terminates in a lateral flange 20. This flange 20 as illustrated in the drawing is so con structed as to extend below and preferably beyond the socket portion of the stop. Also, as illustrated, the stop member may be constructed to include a wall 21 extending upwardly from the flange 20 and transversely of the body of the stop. The purpose of this wall 21 and the extension of the flange will hereinafter more fully appear.

The improved window stop also includes a pin, such, for example, as is illustrated in Fig. 5. In the form of the invention as illus trated this pin is made to include a section 22 which is square in cross section, a section 23 which is cylindrical, another section 24 which is also square in cross section, and a section 25 which is cylindrical in cross section. The pin furthernunie is suitably fitted at both ends thereof with heads indicated at 26 and 26'. The pin is appreciably longer than the bracket member 14. The square section 22 of the pin is adapted normally to lie within the socket 16 of the bracket and to extend appreciably into the socket 19 of the stop member. The section 24 of the pin is adapted normally to lie partially in the socket 19 of the stop and within the socket 17 of the bracket.

These positions of the parts are clearly illlustrated in Fig. 2 wherein the head 26 of the pin lies against the upper face of the socket 16 and the lower head 26 of the pin lies appreciably below the socket 17 and is spaced from the extension of the flange 20 and also from the transverse wall 21. The square sections of the pin are sufficiently smaller than the corresponding sections of the sockets to cause the pin to slide easily in the sockets.

In the use of the window stop as hereinbefore described, the stop member may be placed or set in the position shown in Figs. 2 and 3 wherein the lower portion of the stop member including the flange 20 extends across a portion of the upper transverse rail 12 of the lower window sash; whereby depending upon the position in which the bracket 14 is connected to the upright rail of the upper window sash the movement of the lower window sash is limited inasmuch as when raised to the distance to which it is limited the upper rail of the lower window sash will strike against the lower portion of the stop. It will also be understood that due to the cross section of the pin and the sockets into which it fits the stop member is fixed in this position relatively to the bracket until the pin is removed or its position changed in such a manner that the stop member is permitted to move relatively to the bracket. With the use of the form of the pin as illustrated it will also be understood that when the pin is raised to the position shown in Fig. 4 in which the lower head 26 contacts with the under surface of the socket 17 the round or cylindrical section 23 of the pin lies within the socket 16 and the round or cylindrical section 25 of the pin lies within the socket 17 whereby the stop member may be turned from the position shown in Figs. 2 and 3 to a right angle to that shown in Fig. 4, moving the pin, of course, in like manner.

lVhen moved to the position as shown in Fig. 4 the pin may be caused to assume its original and normal position in which the head 26 lies against the upper face of the socket 16 thereby causing the square sec tion 22 of the pin to again lie within the socket 16 and a portion of the socket 19 and the square section 24 of the pin to lie partially in the 7 socket 19 and to extend through the socket 1'7 and to again lock or fix the stop member 18 in its position relatively to the bracket member 14. In this position, it will also be understood that the window sashes may be moved freely to any desired position inasmuch as then the upper, as well as the lower rail of the lower window sash will clear the stop member. The extensions of the flange 20 and the transverse wall 21 are employed to prevent the use of a tool or other implement in engaging the lower end of the pin for raising the same and thus making it possible to swing the stop member 18 from one position to another.

Inthe form of the invention, as hereinbefore described, the extent to which the lower sash of a window may be moved when the stop member is set for this purpose is determined by the position of the bracket on the upright or vertical rail of the upper sash of the window. The present invention also contemplates a structure in the use of which the stop member may be set in different positions so as to make it possible to vary the distance to which the lower sash may be moved relatively to the upper sash without shifting the position of the bracket and also for locking the window sashes when closed. For example, as illustrated in Figs. 6, 7, and 8 the'bracket 27 may be of sutlicient length to include a multiplicity of projections or steps between sets of end sockets. As illustrated this bracket 27 is constructed to include end sockets 28, 29, which are at the ends of the bracket, in alignment with each other and offset from the body of the bracket. Each socket 28, 29 is provided with a multisided bore which is preferably square in cross section. Intermediate of the sockets 28 and 29 there are spaced shoulders or projections and 3i in alignment with the body of the bracket.

In this type of window stop there is a pin having a head 32 at one end thereof, a section 33 which is of square cross section, a section 34 which is cylindrical, a relativc ly long section 35 which is also square in cross section and an end section 40 which is cylindrical and which at its extremity is fitted with a head 41. Associated with the bracket- 27 and its head there is a stop 42. The stop 42 is similar in all respects to the stop 18 hereinbefore described, being formed with a socket 4i3 adapted to lie between either socket of the bracket and the next adj acent projection or between the projections, and with a flange 44 having an extension 45 and also with a transverse wall 46. With the parts in the position shown in Fig. 8 the stop member 42 may be turned to either of its revoluble positions in one of which as shown in the full lines of Fig. 7 it lies partially over the upper transverse rail of the lower window sash, or as shown in dotted lines entirely within the confines of the lower transverse rail of the upper sash so that the sashes are then free to move rela-.

tively to one another. Obviously'this is because the pin is raised to the position in which the head 41 lies against the lower surface of the socket 29 and in which position the section 34 of the pin lies within the socket 28, and the section 40 of the pin within the socket 29, making it possible to turn the pin by the movement of the stop member or vice versa. It will also be equally apparent that when the stop member is in either position the pin may be shifted to its normal place or position to lock the stop member relatively to the bracket. In this structure, like the other form of the invention, the head 4L1 at the lower end of the pin, as well as the head 32 at the upper end of the pin, is permanently connected thereto. From the foregoing it will now be understood that the stop member 42, when in the position shown in dotted lines in Fig. 7 and in full lines in Fig. 8, is slidable on the pin from one position to another longitudinally thereof and that in this sliding movement the stop member passes behind or at the rear of the shoulders or projections 30, 31. It follows therefore that when the socket portion of this stop member-registers with the space between the shoulders or projections 30, 31, or between the socket 28 and the projection 30, the pin and the stop member may be turned 90 to bring the stop member to the full line position as shown in Fig. 7 whereupon the pin may be shifted to its other position as shown in Fig. 6, and that then the stop member will be irrevolubly secured in place relatively to the bracket and consequently will act as a stop to determine the extent to which the lower sash may be moved relatively to the upper sash. It will also now be obvious that in the use of this form of the improved window stop, the parts may be set to vary the distance through which the lower sash of the window may be moved relatively to the upper sash thereof, and also that the bracket 27 may be so placed as to use the stop member as a lock when the window sashes are closed.

Furthermore, it is to be noted that obvious changes in the construction of the device as described may be made, for example, the socket members may be reversed, that is, the spaced sockets placed on the stop member and the single socket placed on the bracket, or both the stop member and the bracket may be provided with spaced sockets adapted to interfit with each other without departing from the nature and spirit of the invention.

I claim as my invention:

1. In a window stop, a bracket having spaced sockets with multisided bores, a stop member having a socket with a multisided bore, and a pin having multisided parts and parts of smaller cross section than the multisided parts, the said pin being slidable in the said sockets and in one position revoluble in thesockets of the bracket and in another position non-revoluble in the sockets of the bracket, the said pinbeing non-revoluble in the socket of the stop member whereby when thepin is in position to be revoluble in the sockets of the bracket the stop member is revoluble therewith and the pin is thus adapted to fixedly connect the stop member to the bracket in a plurality of positions in one of which the stop member is so placed as to per-' mitthe passage of the sash rails and in another of which the stop member limits the relative movement between the said sash rails.

2. In a window stop, a bracket having spaced sockets with square bores, a stop member having a socket with a square bore, and a pin having a part of square cross section at one end, a part of smaller cross section at the other end and intermediate parts of square and smaller cross sections, the said pin being slidable in the said sockets and when in one position having the part of square section at one end thereof extending through one of the sockets of the bracket and into the socket of the stop member while the intermediate part of square section extends through the other socket of the bracket and into the socket of the stop member, and when the pin is in another position the parts of smaller cross section lie within the sockets of the bracket member sothat then the pin and stop member may be turned to one of a plurality of positions.

3. In a window stop, a bracket having spaced sockets with square bores, a stop member having a socket with a square bore, and a pin having an upper part of square cross sec tion, a lower part of smaller cross section and intermediateparts of square and smaller cross sections, the pin being slidable in the said sockets and when in its lower position having its upper part of square section extending through the upper socket of the bracket and into the socket in the stop member, and its intermediate part of square cross section extending through the lower socket of the bracket and into the socket of the stop member whereas in its raised position the lower part of smaller cross section lies within the lower socket of the bracket and the other part of smaller cross section lies within the upper socket of the bracket.

4:. In a window stop, a bracket having spaced sockets, the said sockets being olfset from the bracket, placed in alignment with each other and having multisided bores, a plurality of shoulders extending in spaced positions from and in. alignment with the said bracket and intermediate of the said sockets, a stop member having a socket adapted to extend between either socket of the bracket and next adjacent shoulder as well as between any pair of the said shoulders, and a pin having alternate multisided parts and intermediate parts of smaller cross section adapted to lit and move longitudinally in the sockets of the bracket and stop member to connect the same in such a manner as to permit the stop member to slide by any of the shoulders and to connect the stop member to the bracket in such a manner that when the pin is in one position the stop member is irrevolubly connected to the bracket and when the pin is in another position the stop member and pin are revoluble relatively tothe bracket, the stop member being so constructed that in one position it permits the passage of the sash rails of the window and in another position it limits the movement of one sash rail relatively to the other.

5. In a window stop, a bracket having spaced sockets, the sockets being offset from the bracket, in alignment with each other and having square bores, a plurality of shoulders extending from the bracket in alignment therewith and lying in spaced positions between the said sockets, a stop member having a socket with a square bore therein and adapt-- ed to fit between either socket of the bracket and the next adjacent shoulder as well as between any pair of the said shoulders, and a pin having a square end at one extremity, an intermediate part of square cross section and an intermediate part of smaller cross section, the said pin being slidable in the said sockets and when in one position the parts of smaller cross section lie within the said oflset sockets of the bracket to permit the pin and the stop member to turn together, whereas when in another position the said intermediate part of square cross section lies within the bore of the ollset socket at one end of the bracket and the said square end within the bore of the other offset socket of the bracket, a portion at least of the said intermediate part of square cross section of the pin lying at all times within the bore of the socket of the stop member.
